People cannot be anywhere in the radius of the kite cable. Kinda limits where is can be deployed. But the quick deployment could work for some situations.
This is not correct. Untrained people can't be inside the flight zone while operating. This is roughly the downwind quarter of the potential flight zone.
Even a quarter is a huge area. Using the "safety buffer" radius of 425m, that is 560k m2 or 140 acres. A quarter of that is 35 acres, for 30 kW.
For regular wind turbines, it's 30-70 acres per MW generated. That is 20x-40x more power for the same land area. And almost all the land under a wind turbine is freely usable.
The same kind that makes you immune to crashing a car, none. However the training presumably could help you asses and mitigate risks better than someone with no training.
